Spots at f/22

It might be time to clean the sensor of my camera again. The circles in the photo above are the spots I removed in Lightroom. They’re caused by little specks of dirt or dust on the camera sensor.

Thankfully they’re really only visible when shooting with a closed down aperture like f/22. At f/8 I see nothing! The aperture of a lens describes how big the hole in the lens is that lets light in to the camera sensor or film. Paradoxically, small f numbers are big holes, so f/1.8 lets in lots of light, while f/22 creates a tiny hole and not a lot of light gets through.

Even if you never take the lens off your camera, you might still get spots on your sensor. A zoom lens has bits that go in and out. Air goes in and out and there’s a (tiny) chance that dust will get sucked in. Dust in the lens itself is nothing to worry about as it’ll never show in photos but if you shoot a lot at small apertures like f/22 you can clean your sensor.

It’s actually not that hard to clean the sensor. Last year I wrote a blog post on how to clean your camera sensor including a video and step by step instructions. I’ll probably get around to that this week again. Go have a look if you see spots, or go see a doctor if you’re not looking at a photo at the time …

MacOS Sierra and Lightroom 5

If you updated your Mac to MacOS Sierra and you use an old version of Lightroom you may get a shock when you try to import anything.

The destination and rename panels are missing from the sidebar! Luckily there’s an easy way to fix it, at least temporarily, thanks to The Lightroom Queen who figured out how. Right click on one of the panel headers and you can enable the missing panels again in the menu that appears!

Unfortunately the change doesn’t stick and the next time you import photos you’ll have to enable those panels again if you want to check those settings.

I can’t imagine Adobe will update LR5. I didn’t think Lightroom would start to break down so quickly after an OS upgrade as the app isn’t that old but I guess we’ll all have to jump on the Creative Cloud bandwagon sooner or later.
